Westward 2 Inch NPT Pipe Tap
This Westward pipe tap cuts internal threads for 2 inch NPT connections using high speed steel construction. The taper design produces a 75 percent thread depth suitable for pipe and conduit fitting. Seven flutes provide chip clearance during hand or machine threading operations.
7 Flutes and 75 Percent Thread Depth
The seven flute geometry distributes cutting load across multiple edges for smoother thread formation in ferrous and non ferrous materials. Bright uncoated high speed steel maintains hardness at typical tapping speeds without coating wear concerns. Thread length of 1 3/4 inch limits effective engagement to that depth per pass.
2.1875 Inch Drill Size Requirement
Correct hole preparation demands a 2.1875 inch drill bit to achieve the specified 75 percent thread height for Class 3B fit. Using an undersized drill increases torque and risks tap breakage while oversized holes produce shallow threads that may leak under pressure.

Questions about this item
Will the 2"-11-1/2 NPT tap fit the existing threads on my older pipe fittings?
The tap cuts a standard 2"-11-1/2 NPT taper thread. Match it against the fitting's thread specification; if the fitting is also NPT with 11-1/2 threads per inch, the new threads will engage correctly.
How can I verify the 7-flute tap is cutting clean threads at the 1 3/4 in thread length?
After tapping, inspect the threads with an NPT thread gauge. A correct 3B class fit shows full thread form over the 1 3/4 in length without tearing, and the 7 flutes should leave a smooth surface finish.
Does the box include the 2.1875 in drill bit for the 75 percent thread depth, or must I buy it separately?
Only the high-speed steel pipe tap is supplied. The 2.1875 in drill bit required for the 75 percent thread drill size is not included and must be purchased separately.
